Decision tables are the most common element from DMN. They are easy to use and can solve many problems. However, DMN has more elements like Business Knowledge Models, Contexts, Literal Expressions, Function Definitions, Invocations and more. In this post, I want to introduce the new extension for DMN and show how it can be used to model an example decision with the full power of DMN.

In Camunda, you can use scripts at different places of a process. For example, inside a Script Task, as an execution/task listener, as a condition expression on a sequence flow or inside an input/output mapping. Usually, the scripts are written in JavaScript, Groovy or JUEL. Using the FEEL extension, it is also possible to write scripts in FEEL (Friendly Enough Expression Language) which is a part of the DMN specification.

I’m happy to announce the first release of the new community extension FEEL-Scala. FEEL is a part of the DMN specification of the OMG and stands for “Friendly Enough Expression Language”. It provides a simple data model and a syntax designed for a wide audience. The new community extension implements a large feature set of FEEL and replaces the default FEEL engine of the Camunda DMN engine.

8 Months ago, we created a benchmark for the DMN engine and measured the number of decision tables the engine can evaluate per second. Now, we had a second look at it to find a way to make the DMN engine even faster. In our benchmarks we see improvements in throughput of up to 6x.

Since emails are a common form of communication, processes may also interact with them. For example an order process can start when a new order is received via email or an email is sent at the end which contains an invoice. The extension camunda-bpm-mail makes it easy to integrate emails in a process and interact with them.

I created a Get Started Guide for Developers who are new to DMN. It guides you through modeling a DMN 1.1 decision table and executing it with the Camunda BPM Platform.
